Abstract
Embodiments of the present invention disclose a parallax barrier, a designing method thereof and a parallax barrier type 3D display device. The parallax barrier comprises: a plurality of grating sheets, utilized to shield light, disposed in an arrangement direction and spaced apart from each other, wherein the plurality of grating sheets are divided into 2K identical grating sections each of which comprises two or more grating segments, each grating segment comprises one or more grating sheets with an identical grating pitch C, and the grating sheets included in different grating segments have different grating pitches, and the 2K grating sections are arranged symmetrically about a center line of the parallax barrier in the arrangement direction, and K is a natural number.
